Detail Information
JRB Steel Special Mark Buoy


JRB-SSMB show a special area or feature. For example, to show that a channel divides or to mark cables or pipelines. They can also mark a channel within a channel. For example, a channel for deep draught ships in a wide river or bay where the limits of the channel for normal navigation are marked by red and green lateral buoys or beacons. All our buoys are in line with IALA guideline and recommendation. We can supply the certificate of CCS.

The thickness of steel plate for its construction is greater than 10 mm. Float diameters available from 0.6 to 3 meters are submitted to an antioxidation treatment. They are characterized by their high shock resistance and stability. Metallic parts of the buoys (superstructure and tail) are made from hot-dip galvanized steel, and designed to provide a long service life under harsh marine conditions. They can be customized under client’s request, as well as to be made from stainless steel or marine aluminium.
